 * A TemplateViewRoute is built up by a path.
 * TemplateViewRoute instead of returning the result of calling toString() as body, it returns the result of calling render method.
 * The primary purpose is provide a way to create generic and reusable components for rendering output using a Template Engine.
 * For example to render objects to html by using Freemarker template engine..
